Mod's if this is in the wrong place please move it to its correct location.
I sat down in a plastic lawn chair with my Isle of Man box-pleat on the other day and didn't notice the chair had some dirt and some water, anyway there is a small dried spot in the middle of a pleat. It appears to have soaked through. Its very small but I want to get it out! How's the best way? Cold water and dabbing the clothe? Warm water?

thanks,
dave
